Reporting their peer-reviewed findings in the latest issue of the journal Science, Dr Kostya Novoselov and Professor Andre Geim from The School of Physics and Astronomy at The University of Manchester ...

Graphene can be built in atomic thickness (an atom or two atom thick graphene sheets can be prepared) but the challenge here is to make graphene work like electronic devices such as diode, transistor, ...

Quantum effects such as tunneling and atomistic disorder dominate the characteristics of these nanoscale devices The first transistors built in 1947 were over 1 centimeter ... along with electric ...

The smaller the transistors and logic ... atomically thin flakes of graphene, hexagonal boron nitride and chromium triiodide on top of each other to form tunnel junction devices — which they ...

The porphyrin is sandwiched between two graphene electrodes ... by eliminating the leaky electron flow from quantum tunneling through the transistor when it is supposed to be switched off.

In simple terms, the most promising devices on Intel’s current list are narrowed down to five technologies—spin-majority gate; spin-wave devices; III-V tunnel field-effect transistors (TFETs); ...
